Le travail réalisé au cours de cette thèse concerne le développement du système de bobines de l'expérience n2EDM à l'Institut Paul Sherrer (PSI). Le but de cette expérience est de mettre en évidence de nouvelles sources de violation CP à travers la mesure du moment dipolaire électrique du neutron. L'actuelle limite supérieure sur la mesure de nEDM, 2.9 x 10⁻²⁶ e.cm (90% C.L.) à été obtenue par la collaboration RAL-Sussex-ILL en 2006.L'expérience n2EDM vise à améliorer d'un ordre de grandeur la sensibilité statistique en gardant sous contrôle les effets systématiques. Cela requiert la production d'un champ magnétique très uniforme. Les non-uniformités de ce dernier sont en effet responsable de la dépolarisation des neutrons et impliqués dans plusieurs effets systématiques.Dans le premier chapitre, les motivations physiques sont discutées. Le second chapitre décrit le principe de mesure de l'expérience n2EDM, ainsi que l'importance de l'uniformité du champ magnétique. Le chapitre s'achève par une présentation globale du dispositif expérimental. Le troisième chapitre présente le logiciel COMSOL et discute du design et des performances de la bobine B₀, en charge de la production du champ magnétique principal. Dans le quatrième chapitre, le système de bobines correctrices chargées de corriger les non-uniformités du champ magnétique et celles devant produire des gradients spécifiques sont présentées. Finalement, le cinquième et dernier chapitre présente l'étude des dipôles magnétiques localisés et de leur influence sur l'expérience.

This work presents the design of the coils system developed for the n2EDM experiment at the Paul Sherrer Institute (PSI). The goal of this experiment is to reveal new sources of CP violation through the measurement of the neutron electric dipole moment. The current upper limit of the nEDM measurement, 2.9 x 10⁻²⁶ e.cm (90% C.L.) was achieved by the RAL-Sussex-ILL collaboration in 2006. The n2EDM experiment aims at improving by one order of magnitude the statistical sensitivity while keeping under control the systematics effects. It requires to produce a very uniform field, its non-uniformities being responsible of the neutron's depolarization and of severals systematic effects.In the first chapter, the theoretical motivation are discussed.The second chapter describes the measurement principle of the n2EDM experiment, as well as the importance of the magnetic field uniformity. This chapter ends by an overview of the apparatus. The third chapter introduces the COMSOL software and discuss the design and the performances of the B₀ coil, in charge of the production of the main magnetic field. In the fourth chapter, the correcting coils used to suppress the non-uniformities of the magnetic field and the ones which produce specific gradients are presented. Finally, the fifth and last chapter talks about the study of localised magnetic dipoles and their influence on the experiment.

▼ In semiconductor manufacturing, the miniaturization of devices has always been a strong driving force in the industry. Making the individual transistors smaller makes it possible to increase the number of transistors on a given size chip, resulting in greater processing power and data storage capabilities. As the critical dimensions of today’s technology nodes approach the atomic scale, it is no longer feasible to obtain the same progression of increased transistor count through simple scaling. In the memory industry, new innovations are being incorporated into the manufacturing process, such as the verticalization of NAND memory to keep up with the demand for increased transistor density. With these innovations come new processing challenges, such as wet etching in extremely high-aspect-ratio (HAR) structures while maintaining top-to-bottom uniformity. The objective of this work was to create simulations in COMSOL Multiphysics that depict the time-dependent etching progress in HAR structures. A dynamic etching model was developed to predict the lateral recession profile of a HAR polysilicon trench bounded on the top and bottom by silicon dioxide (SiO2) etched by tetramethylammonium hydroxide. The model considered the diffusion of active etchant species, surface charging of polysilicon and SiO2, and reaction byproduct accumulation on the top-to-bottom etching profile. The results of the simulations suggest that the diffusion of reactant species into the trench could influence the top-to-bottom etch uniformity if the reaction order is greater than 1. The surface charging on polysilicon and SiO2 does not appear to affect the overall top-to-bottom uniformity but leads to a localized reduction in the etch rate in the corners of the trench where the polysilicon meets the SiO2. The secondary etching simulation was developed to model the wet etching of thin SiO2 films sandwiched between silicon layers, a structure that is often used to create cantilever microstructures. Etching models of SiO2 in hydrofluoric acid (HF) from the literature were utilized to provide boundary velocities in moving-boundary simulations of a dynamic etching process as a function of local concentrations of etchant species. The influence of the surface charge present on silicon in the Si/SiO2/Si stacked structures on the etch rate of SiO2 was modeled for varied thicknesses of SiO2. The etch rate of thin films of SiO2 was compared to the bulk etch rate without electrostatic interference. The simulations did not suggest that the SiO2 thickness in the stacked structure has a strong impact its etch rate because etch rate is dominated by neutral species.

L'électrolyse haute température de l'eau à l'aide de membranes en céramique conductrice de protons est un processus intéressant pour la production d'hydrogène. Ce processus, qui peut être effectué sans catalyseurs nobles, produit de l'hydrogène pur et nécessite moins d'électricité que l'électrolyse classique à basse température. Le développement futur de ces réacteurs à membrane nécessite des efforts accrus sur la simulation numérique afin d'optimiser la chaleur et les transferts de masse ainsi que la conception de cellules d'électrolyse. Ce travail présente un ensemble d'équations sélectionnées dans la littérature et des démonstrations mathématiques rigoureuses permettant la description des phénomènes de transport dans la cellule et en particulier dans les électrodes qui sont composées de cermets. A partir de ce modèle, une étude paramétrique est conduite de façon à caractériser l'influence des différents paramètres opératoires sur ces phénomènes. Les différentes observations de cette étude permettent de dresser un ensemble d'hypothèses pour le développement de méthodes destinées à la simplification du modèle et à la réduction du temps de résolution. Ces modèles simplifiés permettent la détermination analytique des grandeurs dans l'électrode et ont conduit à la construction de nombres adimensionnels et de longueur caractéristiques du dispositif.

High temperature electrolysis of water by using proton conducting ceramic membranes is an interesting process for producing hydrogen. This process can be carried out without noble catalysts and produces pure hydrogen and requires less electricity than classical low temperature electrolysis. The future development of such membrane reactors requires increasing efforts on numerical simulation in order to optimize the heat and mass transfers as well as the design of electrolysis cells. This work presents a set of equations selected from the literature and rigorously demonstrated for the description of transport phenomena in the cell and particularly in the electrodes which are made of cermets. From this model, a parametric study is conducted in order to characterize the influence of various operating parameters on these phenomena. The different findings of this study provide a set of assumptions for the development of methods for simplifying the model and reducing the time of resolution. These simplified models allow analytical determination of quantities in the electrode and leads to the establishment of dimensionless numbers and characteristics length of the device.

Ce travail présente le développement de spectromètres photoacoustiques pour la mesure de traces de gaz avec des résonateurs de Helmholtz différentiels.La cuve représente le coeur de l'instrument, le laser qui la traverse va créer une onde de pression stationnaire qui sera mesurée par des microphones. Le signal photoacoustique est fonction de la concentration du gaz et la manière dont il sera amplifié va dépendre en grande partie de la géométrie de la cuve. Une méthode aux éléments finis est utilisée pour exprimer cette caractéristique selon les modes et les fréquences propres calculées de la cuve. Les paramètres clés de la cuve sont ainsi calculés, comme la fréquence de résonance, le facteur de qualité et la constante de la cuve. Contrairement à d'autres méthodes de spectroscopie infrarouge, la sensibilité des spectromètres photoacoustiques augmente alors que la cuve se miniaturise. Cette particularité est vérifiée expérimentalement avec un bon accord avec la simulation. La modélisation prouve une nouvelle fois être suffisamment robuste pour être utilisée dans un processus d'ingénierie du spectromètre. Cet outil va en effet permettre d'optimiser les dimensions du résonateur selon les besoins de l'application, soit en privilégiant le maximum de signal, la plus haute fréquence de travail ou encore le plus faible encombrement. De nombreuses cuves ont été développés avec l'aide de la simulation, l'écart observé avec les paramètres expérimentaux est de l'ordre de 15 %. Enfin, les applications actuelles en mesure de traces de gaz demandent de mesurer la concentration d'au moins deux gaz, de façon simultanée, avec des niveaux de détection proche du ppb. Un mode de résonance de Helmholtz particulier est trouvé afin de proposer une mesure multi-gaz. Enfin, la sensibilité est augmentée grâce à un système multi-passages.

This work presents the conception of a photoacoustic spectrometer dedicated to trace gas measurements using a differential Helmholtz resonator. The main component of the instrument is the cell, where a standing wave is produced by a laser excitation and is measured with microphones. The photoacoustic signal is proportional to the gas concentration and the cell shape mainly affects its amplification. A finite element method is used to find this characteristic by calculating the cell eigenmodes and eigenfrequencies.Key parameters of the cell are then calculated, including cell frequency, quality factor and cell constant. Unlike other infrared spectroscopy methods, sensitivity of photoacoustic spectrometers increases by miniaturization process. This particular phenomenon is experimentally verified and is in good agreement with the simulation.Modelization proves again its robustness to be used on an engineering process of the spectrometer. This tool allows to optimize resonator dimensions according to the application, favouring maximum signal, higher working frequency or reduced size. Many cells designed with the help of the simulation are presented, where the observed error with experiments is of the order of…

▼ The freeze plug is a key safety component of the molten salt fast reactor (MSFR), one of six next-generation nuclear reactor technologies being developed under the Generation IV International Forum (GIF). It should be designed to melt if an accident occurs, allowing the MSFR to drain before it incurs structural damage. Two freeze plug concepts have been considered in recent years, in which the plug is melted either through the decay heat produced in the core, or through heat generated by special heating rings and stored in steel blocks adjacent to the freeze plug. Variations consisting of both a single freeze plug, and multiple smaller plugs contained in a metal plate, have been proposed. This work seeks to evaluate the feasibility of these designs and study how parameters such as the sub-cooling of the plug affect melting times. Additionally, an alternative, wedge-shaped freeze plug design is proposed for increased reliability. Simulations performed in COMSOL showed that the decay heat plug melts within 600 s only if placed within 0.01 m of the mixed core flow. Because such a placement makes the plug vulnerable to temperature and velocity fluctuations in the core during regular operation of the reactor, this design is considered unfeasible and is not recommended for further study. On the other hand, melting times under 600 s were possible with the heating ring design for a range of sub-cooling amounts and plug configurations, suggesting that this design is promising. A thin frozen layer was shown to form on top of the metal grate in the multi-plug configurations, preventing heat transfer through the top of the plate. Although the melting behavior of this layer warrants further investigation, its insulating effect was found to generally cause the single-plug designs to melt faster than the multi-plug designs. A simplified, isothermal model of the wedge-shaped plug was simulated using the enthalpy-porosity approach to account for convection. To model the sinking of the wedge, an extended Darcy term approach was developed based on an analytical solution which was validated experimentally, with good agreement. This model shows that melting of the wedge is unsteady, and that melting times depend linearly on the wedge angle and sub-cooling. Unfortunately, melting times of the wedge plug could not be estimated with realistic, non-isothermal, time-dependent boundary conditions. For future study, a customizable numerical solver such as OpenFOAM is recommended, which would allow the sinking of the solid phase to be modeled more robustly through an immersed boundary method.

▼ Vapor sensors have been used for many years. Their applications range from detection of toxic gases and dangerous chemicals in industrial environments, the monitoring of landmines and other explosives, to the monitoring of atmospheric conditions. Microelectrical mechanical systems (MEMS) fabrication technologies provide a way to fabricate sensitive devices. One type of MEMS vapor sensors is based on mass changing detection and the sensors have a functional chemical coating for absorbing the chemical vapor of interest. The principle of the resonant mass sensor is that the resonant frequency will experience a large change due to a small mass of gas vapor change. This thesis is trying to build analytical micro-cantilever and micro-tilting plate models, which can make optimization more efficient. Several objectives need to be accomplished: (1) Build an analytical model of MEMS resonant mass sensor based on micro-tilting plate with the effects of air damping. (2) Perform design optimization of micro-tilting plate with a hole in the center. (3) Build an analytical model of MEMS resonant mass sensor based on micro-cantilever with the effects of air damping. (4) Perform design optimization of micro-cantilever by COMSOL. Analytical models of micro-tilting plate with a hole in the center are compared with a COMSOL simulation model and show good agreement. The analytical models have been used to do design optimization that maximizes sensitivity. The micro-cantilever analytical model does not show good agreement with a COMSOL simulation model. To further investigate, the air damping pressures at several points on the micro-cantilever have been compared between analytical model and COMSOL model. The analytical model is inadequate for two reasons. First, the model’s boundary condition assumption is not realistic. Second, the deflection shape of the cantilever changes with the hole size, and the model does not account for this. Design optimization of micro-cantilever is done by COMSOL.

▼ Through COMSOL modeling and electrode design, positive dielectrophoretic (pDEP) cell trapping for media exchange has been demonstrated on live Chlamydomnas reinhardtii (C. reinhardtii)microalgae cells in regular growth medium in a PDMS-glass microfluidic MEMS device. Dielectrophoresis (DEP) is the force applied to dielectric particles in a non-uniform alternating current (AC) electric field. A DEP force toward the increasing electric field gradient is called positive. In literature pDEP trapping over large areas has been demonstrated with the use of low conductivity suspending media, while for higher conductivity suspending media, such as growth media, the pDEP force is reduced, and less likely to trap and hold microalgae against the hydrodynamic forces during media exchange. Media exchange allows for the removal of cellular waste and replenishment of nutrients. Multiphysics software, COMSOL, was used to model repeating structures suited for trapping of cells over an area of a microfluidic device. For single shell model, dielectrophoretic force on a homogenous sphere in a homogenous medium in an electric field is a function of the sphere radius, particle conductivity and permittivity, medium conductivity and permittivity, and the gradient of the electric field. By assuming the conductivities, permittivities, and the particle geometry remains constant, the gradient of the electric field is the determining factor for the strength of the pDEP force. Modeling the electric fields and the resulting electric field gradient of various interdigitated electrode configurations allowed for the optimization of an electrode structure’s area of higher electric field gradients. The completed microfluidic device consisted of a single channel and a wide growth chamber overlaid over patterned gold-chrome electrodes fabricated using soft lithography and photolithography. The pDEP trapping was successful in trapping C. reinhardtii for media exchange. Advisors/Committee Members: Geiger, Emil J.

Heavy forestry machines have great immediate effect on soil properties. This increases the interest to develop approaches that help understanding better the interaction between the forest machines and the terrain and consequently develop the forwarders to be gentle to the environment. The most predominant indications of soil disturbances caused by harvesting are mainly rutting and soil compaction. It is critical to understand and evaluate these damages to be able to protect the remaining trees and improve their tree growth rate. Comprehending the bearing capacity of the soil and the interaction between tire and soil are the key issues to develop forest machines that preserve the terrain. The first step to accomplish this goal is to compare the rut depth theoretical data from empirical models with the rut depth data from a full scale field test, the models suitable to predict rut depth is descripted. Tree roots reinforce the forest floor and significantly increase the bearing capacity of the soil. The contribution from root layer to the soil bearing capacity depends on the number, diameter, orientation of the roots and their mechanical properties. To improve the root tensile strength model, a root bending and stretching laboratory test has been carry out and compared with FEM-based results. The existing Valmet 860. 3 Adams MBS model is finally used to study the suitability of the model to predict rut depth. A comparison between several existing methods to predict rut depth is also shown.

Tunga skogsmaskiner har stor omedelbar effekt på markens egenskaper. Detta ökar intresset för att utveckla strategier som underlättar förståelsen av samverkan mellan skogsmaskiner och terrängen och därmed utveckla framdrivning av dessa maskiner som är skonsam mot miljön. De dominerande indikationerna på markstörningar orsakade av hjulbaserade skogsmaskiner är främst spårbildning och jordkompaktering. Det är viktigt att förstå och utvärdera dessa skador för att kunna skydda de kvarvarande träden och förbättra deras tillväxt. Att förstå markens bärighet och samspelet mellan däck och mark är de viktigaste frågorna för att utveckla skogsmaskiner som skonar terrängen. Det första steget för att uppnå detta mål är att jämföra spårdjup vilka är framtagna med empiriska modeller med data för spårdjup från ett fullskaligt fälttest, där de modeller som lämpar sig för att förutsäga spårdjup är beskrivna. Trädrötter förstärker skogsmarken och ökar avsevärt jordens bärighet. Bidraget från rotlagret till jordens bärförmåga beror på antalet rötter, deras diameter samt rötternas orientering och deras mekaniska egenskaper. För att förbättra modellen för rötternas mekaniska egenskaper har rotböjning och rottöjning studerats i ett laboratorietest och vidare jämförts med FEM-baserade resultat. Den befintliga MBS modellen av skotaren Valmet 860.3 har slutligen används för att studera lämpligheten av modellen för att förutsäga spårdjup. En jämförelse mellan flera olika metoder för att förutsäga spårdjup visas också.

La modélisation du transport réactif dans les milieux poreux implique la simulation de plusieurs processus physico-chimiques : écoulement de phases fluides, transport de chaleur, réactions chimiques entre espèces en phases identiques ou différentes. La résolution du système d'équations qui décrit le problème peut être obtenue par une approche soit totalement couplée soit découplée. Les approches découplées simplifient le système d'équations en décomposant le problème sous-parties plus faciles à gérer. Chacune de ces sous-parties peut être résolue avec des techniques d'intégration appropriées. Les techniques de découplage peuvent être non‑itératives (operator splitting methods) ou itératives (fixed‑point iteration), chacunes ayant des avantages et des inconvénients. Les approches non‑iteratives génèrent une erreur associée à la séparation des sous-parties couplées, et les approaches itératives peuvent présenter des problèmes de convergence. Dans cette thèse, nous développons un code sous licence libre en langage MATLAB (https://github.com/TReacLab/TReacLab) dédie à la modélisation du la problématique de la carbonatation atmosphérique du béton, dans le cadre du stockage de déchets de moyenne activité et longue vie en couche géologique profonde. Le code propose un ensemble d'approche découplée : classique, comme les approches de fractionnement séquentiel, alternatif ou Strang, et moins classique, comme les approches de fractionnement additif ou par répartition symétrique. En outre, deux approches itératives basées sur une formulation spécifique (SIA CC et SIA TC) ont également été implémentées. Le code été interfacé de manière générique avec différents solveurs de transport (COMSOL, pdepe MATLAB, FVTool, FD scripts) et géochimiques (iPhreeqc, PhreeqcRM). Afin de valider l'implémentations des différentes approches, plusieurs bancs d'essais classiques dans le domaine du transport réactif ont été utilises avec succès. L'erreur associée à la combinaison du fractionnement de l'opérateur et des techniques numériques étant complexe à évaluer, nous explorons les outils mathématiques existants permettant de l'estimer. Enfin, nous structurons le problème de la carbonatation atmosphérique et présentons des simulations préliminaires, en détaillant les problèmes pertinents et les étapes futures à suivre.

Reactive transport modeling in porous media involves the simulation of several physico‑chemical processes: flow of fluid phases, transport of species, heat transport, chemical reactions between species in the same phase or in different phases. The resolution of the system of equations that describes the problem can be obtained by a fully coupled approach or by a decoupled approach. Decoupled approaches can simplify the system of equations by breaking down the problem into smaller parts that are easier to handle. Each of the smaller parts can be solved with suitable integration techniques. The decoupling techniques might be non‑iterative (operator splitting methods) or iterative (fixed‑point iteration), having each its advantages…

L’objectif de ce travail est d'étudier expérimentalement la formation du capillaire durant le perçage et le soudage par faisceau laser, et de développer une simulation numérique permettant de reproduire la dynamique de formation et d'évolution du capillaire. Nous avons fait le choix d’utiliser comme matériau test le Zinc, en raison de ses propriétés thermodynamiques. Afin de simplifier le problème, nous avons étudié dans un premier temps le mécanisme de perçage. Deux méthodes expérimentales ont été utilisées pour caractériser l'évolution de la géométrie du capillaire : La méthode DODO (Direct Observation of Drilled hOle ) permet de visualiser le capillaire après perçage pour différentes durées et la méthode Zn-Quartz permet d’observer directement son évolution temporelle par camera rapide à travers une lame de quartz. Puis nous avons utilisé cette évolution pour mettre au point une simulation du mécanisme de perçage. Après avoir étudié le dépôt de puissance à l’intérieur d’un capillaire en tenant compte des réflexions multiples et estimé l'importance de la perte d'énergie et de matière lors du processus, nous avons développé une simulation en utilisant le logiciel Comsol Multiphysics couplant l'équation thermique, l'équation de Navier Stokes et prenant en compte le déplacement du métal fondu sous l’action de la pression de recul. Dans ce cas, on observe la formation d’un bourrelet important au bord du trou et une augmentation de la profondeur du capillaire. Ensuite nous avons étudié la formation du capillaire durant le soudage laser, c'est-à-dire avec déplacement de la source. A partir des techniques mises en œuvre pour l’étude du perçage nous avons obtenu l’évolution de la forme du capillaire dans le cas du soudage Zn/Quartz. Nous avons réalisé une simulation relativement simple en supposant la géométrie et la température du capillaire connues a priori. Nous avons constaté qu’un modèle simple, modélisant uniquement les transferts thermiques par conduction, permet de bien simuler la forme de la zone fondue pour les couples Zn/Zn et Zn-quartz.

The aim of the present work is to study experimentally the formation of the capillary during the drilling and welding by laser beam and to develop the numerical simulation which allows following the dynamics and the evolution of the keyhole. The zinc was chosen as a test material because its thermodynamical properties are well known. To simplify the problem, in the first place the drilling mechanism was studied. Two experimental methods were used to characterize the evolution of the keyhole: the Direct Observation of Drilled Hole method, which allows the visualization of the keyhole after the application of laser pulses of different durations, and Zn-Quartz method, which allows the direct observation of keyhole evolution with CCD camera through the layer of quartz. Then, the information on keyhole evolution was used to develop the simulation of drilling mechanism. After studying the beam power deposition inside the capillary with taking in account the multiple photon…
